Breast pain in men is a topic that isn’t talked about very much. There are even people who are unaware of the existence of this condition. The good thing is that it usually doesn’t mean anything serious. Even so, it’s not a symptom that should be overlooked.

Males have much less breast tissue than females. Because of this, breast pain has a lower incidence. And although it’s not common, it’s also a possible sign of breast cancer.

It’s important to note that breast pain in men is sometimes confused with chest muscle discomfort. However, both should be observed, because while it may be a passing discomfort, sometimes it’s a sign of something more serious.

The main causes of breast pain in men

The causes of breast pain in men are usually benign. That doesn’t mean that they should be ignored or that they don’t require medical attention.

If the pain is persistent, very intense, or accompanied by other symptoms, it’s best to consult a professional.

1. Injuries

Injuries are the main cause of breast pain in men. Accidentally or while exercising, you may receive a blow to the chest and this causes discomfort. The severity will depend on the intensity and characteristics of the trauma.

In these cases, it’s best to apply a cold compress to the affected area. If the pain does not subside or is so intense that it prevents daily activities, it’s advisable to seek medical attention.

2. Runner’s nipple

The name runner’s nipple is given to a condition that’s caused by the skin rubbing against the shirt when jogging or running for a considerable time. The effect of this is an irritation of the nipples that can even bleed.

It’s best to wear a tight-fitting or close-fitting T-shirt if you’re going to run for several hours. This prevents friction and protects the nipples. You can also put an adhesive on this area when exercising.

Mastitis is an inflammation of the breasts. It causes symptoms such as pain, redness, and swelling.

5. Gynecomastia

Gynecomastia is a condition in which the breasts grow and appear larger than normal. It’s caused by an increase in breast tissue and may occur in one or both breasts. It often includes the presence of a small lump under the nipple.

It’s estimated that this condition affects 50% of boys during puberty. It’s usually accompanied by breast pain in males and should be treated by a physician.

Other causes include the following:

  • Renal insufficiency
  • Testosterone deficiency

Fibroadenoma is a benign tumor of the breast. It doesn’t develop into cancer and very rarely occurs in men.

Cancer only causes breast pain in men when it is very advanced. It’s also common for the breast to appear reddened, swollen, and warmer than normal.

Only 1% of all breast cancers in the world correspond to men. Even so, due to the seriousness, it’s very important to be aware of any lump that appears in the area and to consult a doctor.

8. Other causes

Excessive consumption of alcohol, marijuana, or heroin can cause certain liver conditions that produce breast pain in men. Something similar happens when using products with lavender oil or tea tree oil, although for different reasons.

The importance of breast self-examination in men
